Gears and Grapes Getaways, Inc, San Francisco

On bike tours with Gears and Grapes Getaways, groups cycle through the iconic Napa Valley, internationally recognized as one of the nine Great Wine Capitals in the world, and the slightly-more-indie Sonoma Valley, home to nearly every type of grape grown in California.

Groups typically stop at four boutique wineries during the tours, pausing at midday for a gourmet picnic lunch. Those who get tired of pedaling or who want to pretend they're on a stakeout can hop on the shuttle that follows close behind at any time. Guides also take visitors on tours of wineries and breweries in San Francisco proper.
